| Abstract: | A new hiding algorithm is given, in which the secret image is scrambl before image hiding. The statistic char- acteristic and energy distribution of coefficients are analyzed. Theory of noncommutative wavelet is applied to digital image hiding to accomplish the information blindly extracting. The result of experiment shows that the new algorithm has better SNR. |
| Keywords: | noncommutative wavelet information hiding blind detection |
